We alwa= ys zero-fill invalid parts of the partially-valid pages that are mapped into userspace. Was there a history behind the SIGBUS requirement ? I believe that the cha= nge for SIGBUS->SIGSEGV came with r151316, and I cannot remember such explicit language at that time. Anyway, I am certain that we do not want to change the signal definitions b= ack, because there are programs that depend on it and which already did the swit= ch to accommodate to the change. --=20 You are receiving this mail because: You are the assignee for the bug.=
